Irregular pigmented structures in a basal cell cancer

plain view of this image.

This basal cell cancer (histologically confirmed on excision, but it couldn’t have been anything else from the dermoscopy) demonstrates a pink background, typical vessels, and irregular pigmented structures at top and bottom. Under the plain view, which shows a pink papule with darker pigmentation at one end, I have posted the original dermoscopic image plus 2 edits, one using the autocorrect and the other fiddling with brightness and contrast, both with Office picture manager. I think editing and enlarging the image can sometimes help make the whole image brighter and subtle features clearer, I wouldn’t go further than that. There is a lot of technical research work to be done on taking quality dermoscopic images and studying them carefully on the screen where they can be blown up and edited. Obviously you’re not going to use Paint or Photoshop to add stuff that wasn’t there, but this isn’t cheating, its only adjusting the light and shade. I often find that, having seen more with the scope in clinic that the naked eye, I then see more again when I view the image on the screen. Especially dots and smaller globules.

The above image of this BCC was altered by the MS office picture manager autocorrect. It certainly makes the pink/white body of the tumour stand out more from the normal (in fact quite badly sun damaged ) skin.

    Great image and important point. I do wonder the role of image editing;
    The cynic in me likens it to statistics – torture by numbers/ torture by pixels? Do you ‘improve’ your images much often and ever proven wrong by histology?

      no and yes. But neither very often.
